WEAR-RESISTANT INTERFACE ASSEMBLY, PARTICULARLY A WEAR-RESISTANT CHAIN OR ROLLING BEARING

摘要

A chain conveyor assembly having the combination of a polymeric material and a hard diamond-like coating at the frictional interface of the chain links. Th e conveyor chain preferably includes male and female links connected to one another by connector pins (20). The shaft of each connector pin (20) is coat ed with a diamond-like coating having high hardness, low friction and low wear characteristics. Opposite ends of the connector pins (20) are connected to t he female link while the shaft (52) of the connector pin (20) passes through th e male link. A polymeric bushing (18) is fitted to the male link in engagement with the shaft (52) of the connector pin (20). Accordingly, relative movemen t between the links occurs at the interface of the DLC connector pin (20) and the polymeric bushing (18).
